minutely pustulate on the nether side, short petioled or 

 subsessile; midrib purple even on the upper more or 

 less carinate side, very strongly carinate beneath, gla- 

 brous; lateral nerves much ascending, straight, slightly 

 more evident on the lower side; petiole 1 cm. long, 

 carinate and giabrate beneath, caniculate above; sheath 

 glabrate or pulverulent, the edges membranous, two thirds 

 clasping the stem; ligular stipule projected from the upper 

 end of the sheath sides, submembranous except at the basal 

 portion, oblong, striate or obscurely carinate, obliquely 

 obtuse at the apex, 2 cm. long by 7 mm. wide. In- 

 frutescence subglobose, 5 to 8 cm. across, upon a 2 cm. 

 thick red bracteate ascendingly curved peduncle arising 

 from the rhizome near the stem base; carpels subsessile or 

 upon short thick pedicels, subtended by unequal persis- 

 tent oblong reddish bracts, hard, dull red, 25 cm. long 

 by 1.5 cm. thick, angular and tapering toward the base, 

 obscurely costate, short yellowish canescent, terminated 

 by a large stout calyx portion, the apical part very 

 irregularly excrescent or ridged and bluntly muricate; 

 seeds 2 mm. across, angular, blackish brown, smooth.

 zon, August, 1916. 



Confined to moist stony earth of steep densely wooded 

 and shaded cuts or gulches near the water courses at 

 1500 feet altitude. 



Allied to Hornsttdtia pandanicarpa (Elm.) Elm. which 

 has a thick rim about the apical portion of its carpels, 

 and whose ligular stipules are entirely different. Our 

 present new species is unique in its purple to atropur- 

 pureus nether leaf surface. The author has observed a 

 number of these plants clinging to almost precipitous 

 slopes, and all leaves of whatever age are colored be- 

 neath. Looking up from the creek bed they appear gor- 

 geous, but looking down upon them from above the colo- 

 ration can not be detected. 



Kornstedtia sorsogonensis Elm. n. sp. 



Coarsely clustered perennial. Stems 2.5 cm. thick, te- 

 rete, 4 m. long, ascending. 2 to 3 times as thick at the en, 

 larged base, connected with rhizomes. Roots dirty yellow- 

 wiry and rigid, from the lower side of the rootstocks 

 and bulbose stem bases; rhizome stout, horizontal. 1.25 

 to 2 cm. thick, yellowish brown bracteated. Blades chiefly 

 ascending, closer set and narrower toward the top, scatter- 

 ing and much reduced below the middle and toward the
